It's optional; it can contain any valid JSON. The idea is that you can
load that JSON and thus do some inquires about the plugin _without_
dlopening the plugin itself, by using QPluginLoader::metaData. For
instance, for an image plugin, you could figure out what are its
supported image formats without the need to load the plugin, create an
instance of some object and call some virtual method.
